and the body shows the following /bin/sh: /var/log/ispconfig/cron.log: Permission denied

Naturally I went and checked the permission settings for cron.log and the permissions are set to 666; I am a little confused on why this has started happening since I haven't made any changes for many weeks, I am running centos 5.6 and I've disabled the getmail cron while I try and work out the cause of this problem.

I have also been looking into another issue regarding the virus software being outdated; I can just ignore this right?
